Set D4 H Activity 1
ACTIVITY
Predict & Fill
Overview
Students predict which of 3 containers holds the most
water and which holds the least Then they check their
predictions by illing each, using a 3-ounce drinking cup
as measuring tool
Skills & Concepts
You’ll need
H Predict & Fill Record Sheet (page D4.3, run a half class
set, plus extras as needed)
Preparation)
H cafeteria tray
Advance Preparation Clear containers are best, but practically any plastic container that holds 12–30 liquid ounces will do Try to ind containers of different shapes and sizes (i.e., tall and narrow, short and wide, curved sides, rectangular, and so on) Use a permanent marker to label each container with an alphabet letter
Instructions for Predict & Fill
1 Choose 3 containers from your collection that are very different in shape but reasonably close in ca-pacity (within a few ounces of one another) Place the containers on a tray, along with the plastic tub of water, a 3-ounce paper drinking cup, and a funnel if you have one Set the tray in the middle of your dis-cussion circle and invite the children to join you Ask them to bring their pencils and clipboard (or other hard writing surfaces) with them
2 Hold up the 3-ounce cup and explain that you’re going to use it measure the capacity of each con-tainer Ask students to examine the 3 containers carefully and predict which will hold the most and which will hold the least water Ask them to pair-share their predictions and then invite volunteers to share their thinking with the class
Students I think F will hold the most Even though B is taller, it curves in at the top, so I don’t think
it’ll hold as much
Trang 4Set D4 Measurement: Capacity
I think maybe D will hold the most It’s the shortest, but it’s pretty wide going one way
I say jar B because it’s the tallest.
3 Distribute copies of the Predict & Fill Record Sheet Review the sheet together, and then ask each stu-dent to write the letter of one of the containers in each of the three boxes at the top Encourage the chil-dren to think for themselves, even if their predictions don’t match those of the people near them
Set D4 Measurement: Capacity Blackline Run a half class set plus extras as needed
Predict and Fill Record Sheet
1 Which container do you think will hold the most? Which will hold the least?
2 How much does each container hold? (Use 3-ounce cups to measure.)
a Container _ holds _ 3-counce cups of water
b Container _ holds _ 3-counce cups of water
c Container _ holds _ 3-counce cups of water
3 Which one really holds the most? the least? Show the results below
4 Choose a helper to fill one of the containers using the 3-ounce cup while the rest of the students watch, count, and record the results on their sheets Remind your helper to fill the 3-ounce drinking cup
to the very top each time before pouring it into the container
5 Repeat step 4 with the other 2 containers, choose a new helper each time
6 Ask students to record the results at the bottom of their sheet Which container actually held the most? Which one held the least? How do they know? Were they surprised?
7 Place the tray of materials on a table or extra desk, along with copies of the Predict & Fill Record Sheet and the other plastic containers you’ve collected Ask students to work individually or in pairs during Work Places over the next couple of weeks to try this measuring experiment for themselves En-courage them to try different combinations of containers
